s. s. KARAVIA COMBINATION LOCK Filed June 12, 1943 FIGQ Sopms 81 K4 RA WA 7 'INVENTOR ATTORNEY Patented F eb. 5, 1946 UNITED STATES PATENT OFFICE COMBINATION LOOK Sophie S. Karavia, New York, N. Y. Application June 12, 1943, Serial No. 490,611 1 Claim. (01. 76-66) My invention relates to combination locks and has particular reference to locks in which a series of rotatable discs is employed for locking and releasing a locking mechanism, the unlocking position of the discs being indicated by suitable symbols.

My invention has for its object to provide a combination lock especially suitable for locking handbags, brief cases and similar containers. The lock for this purpose is provided with a relatively flat main body which can be permanently at tached to the outer flap or cover of a container, the body being provided with a sliding locking bar engaging a keeper attached to the body of the container. The bar can be moved manually into the operative position and locked in such a position by turning at random combination discs on the body. For unlocking the bar, the discs must be placed in a definite position indicated by a certain combination of the symbols on the discs. When applied to a handbag, the body of the lock may be attached to the upper bar of the frame of the bag, the lock engaging a corresponding slot in the other bar of the frame.

My invention is based on the combination mechanism disclosed in my United States Patent No. 2,231,536.

My invention is more fully described in the accompanying specification and drawing in which Fig. 1 is a vertical sectional view of my lock attached to the frame of a handbag;

Fig. 2 is a front view of the lock partly in section;

Fig. 3 is a bottom plan view of the lock;

Fig. 4 is a detailed view of the second combination lock;

Fig. 5 is an edge view of the same;

Fig. 6 is a detail view of the top disc;

Fig. 7 is a sectional view of a modified look as applied to a brief case;

Fig. 8 is a front view of a handbag with my lock.

My combination lock consists of a main body I in the form of a fiat disc having threaded holes 2 for attaching the body to the upper portion of the frame of a handbag 3 as by screws 4, although rivets and similar fastenin means may be also employed. The body has a slot 5 in the outer side for a sliding bar 6. The latter extends beyond the edges of the body and can be manually shifted into an operative or inoperative position. A hook 1 is attached to the bar, extending through an opening 8 in the body I and adapted to engage a slot 9 in the other side of the frame of the handbag, the edge of the frame at the slot forming a keeper for the lock. The opening 8 is sufliciently large to allow free movement of the hook I so that in the operative position of the locking bar 6 the hook I fully engages the slot 9, and in the inoperative position of the bar the hook is withdrawn from the slot 9 so that the bag can be opened. A cap I! attached to the under side of the body I as by screws I2, encloses the hook in its inoperative position.

A pin or lug I3 extends from the upper side of the bar, being formed integrally with the hook I, and passes through arcuate slots I4, I5, I6 in combination discs I'I, I8 and I9, rotatively mounted on a pin 20. The inner end of the pin is fastened to the body I at 2I as by riveting, the outer end of the pin I3 having an enlarged head 22, resting in a corresponding recess in a cap 23. The pin is shouldered at the point of entrance into the base plate or body I so that the discs are not jammed and are free to rotate on the pin. The discs areprovided with numerals or symbols 24 at the periphery for placing the discs in a position in which the bar 6 is unlocked.

The discs have slots 25 connecting the two adjacent arcuate grooves, the width of the slot being suiiicient to admit the pin or lug I3. As may be seen, the bar 6 is free to move between operative and inoperative positions only when the slots 25 in all three discs are aligned with the bar 6. The pin I3 then can pass freely through the slots 25, allowing the bar 6 to be moved up or down, as from the slots I4, I5, I6, into slots 30', 3|, 32.

A modified construction of the device is shown in Fig. 7, the keeper 26 being in the form of an eye on a base 21, riveted to a wall 28 of a container such as a brief case or the like. A recess 29 is provided in the base for the hook and. also to receive the keeper 26 in the form of an eye adapted to be engaged by the hook I. The keeper has a fiat base 33 attached to the wall 34 of the brief case.

My combination lock can be used with a variety of containers such as handbags, brief cases, traveling bags, golf or tennis bags, instrument cases, etc.

It is understood that my combination locks may be further modified without departing from the spirit of the invention, as set forth in the appended claim.

I claim a my invention:

A combination lock for joining two members together, comprising a base plate adapted to be attached to the outer side of the first member; a locking bar movably supported in the base plate,

operative position; a, plurality of discs rotatively mounted on the base in planes parallel to the bar with arcuate slots; a lug extending from the bar through the slots; and. bridges between the slots 5 for locking the bar in an operative position.
